I guess it's also a question of if the chili bits are still spicy. I bet you could do it, though it might need more flour to balance it out?

Fresh soy milk is a bit bean-y, with a clean sweet aftertaste! Often it's either sweetened or soy sauce/vinegar/toppings are added to coagulate it into a thin savory soup with tiny tofu-like bits.

If you do tomato soup, would highly recommend the classic grilled cheese combo.
